It will be apparent that the parts that become warped or worn and require replacement, may readily be separated and detached "from remaining parts, andreplacements and repairs may bemade with facility. The simplicityof construction provides'vfor facility in assembling the grate, and also in disman- Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is 1. The combination with a pair of bearing bars each having integral lateral heads and complementary interlocking tongues and grooves onadjoining faces of said heads,- of

' I removable grate-bar end sections and anintel-mediate section, oo-acting retaining means on the end sections andbearing bars, and co acting retaining means between said sections.

2. In a furnace gratethe combination with w removable grate barwsections, of a pair of bearing bars, complementary, laterally projecting heads integral with each of said bars,

and complementary tongues and grooves on adjoining 'faces of said heads. v
